Surface quality
Surface quality depends on surface finish group.
| Surface finish group | Surface finish properties/ Surface roughness | Surface condition characteristics |

The surface imperfections are not allowed on the bottom surface of strip when its depth exceeds 1/4 of sum of limit tolerances on thickness; contamination spots, annealing color and gray spots are also not allowed. |
| II | Regulated on both sides agreement | The surface defects are not allowed on both surfaces of strip when the depth of defects exceeds half a sum of limit tolerance on thickness; annealing color is not allowed in the places located more than 50 mm from the edges. On the face side enter marks and scratches of more than 50 mm length are not allowed. |
| IIIа | Not regulated | The surface imperfections are not admitted on both surfaces when their depth exceeds half a sum of limit tolerances on thickness. Annealing color is not allowed in the places located more than 200 mm from the edges. |
| IIIб | Not regulated | The surface imperfections are not admitted on both surfaces when their depth exceeds half a sum of limit tolerances on thickness. Annealing colour is allowed on the whole surface of material |

Types of packing
Packing of finished products is carried out in accordance with the requirements of GOST 7566-94, GOST 503-81 and schemes agreed with customer on. On customer’s requirement to strip packing in accordance with GOST 503-81, bottom coil is wrapped in polypropylene film. Coils for railway shipment shall be packed in metal boxes in accordance with GOST 503-81. Packing can be done both on vertical and horizontal axis.
Vertical axis packing
Coils from slitting line, wound on a coiler with plastic or metal strap, are laid on a wooden pallet. If a strip width is less than 50 mm, there shall be at least one strapping through an inner coil diameter, packaging an inner end of the strip.
Strip coils with wooden fillers between are put together in piles. Strips wound on single coilers can be laid without fillers between the coils.
In accordance with the scheme strips are wrapped in packing paper or film and strapped to a pallet by 4 packaging steel straps. To prevent from frontal surface deformation plastic pallets are put under packaging seals. Depending on a packing scheme products can be packed in paper or metal box.
Horizontal axis packing
Required number of CR strip coils with marking tags are laid on a pallet and strapped to each other by one or two radial packaging steel straps (through inner diameter).
Strip coils are set with wooden fillers. Strips wound on single coilers can be set without fillers between the coils.
In accordance with the scheme strips are wrapped in packing paper and strapped to a pallet by 2, and not less than 4 on forming, radial packaging steel straps.
Описание
Одним из наиболее востребованных на рынке видов плоского проката является лента оцинкованная, часто также именуемая штрипс оцинкованный или полоса. Для изготовления данного вида продукции холоднокатаный прокат в рулонах покрывают цинком. Нанесение защитного покрытия позволяет увеличить коррозийную стойкость и продолжительность срока эксплуатации металла. Для облегчения веса конструкций и увеличения гибкости изделий в оцинкованной ленте могут делать специальные отверстия – производят перфорирование. Производители ленты из оцинкованной стали выпускают преимущественно неперфорированную оцинкованную ленту.
Область применения
Обычная (неперфорированная) стальная оцинкованная лента находит применение в таких сферах как:
Упаковка продукции – упаковочная или бандажная лента.
Производство строительных конструкций – профиля для фасадов, под гипсокартон и для строительных конструкции ферм и каркасов, в том числе для теплиц и крепления поликарбоната, внешней и внутренней отделки помещений, изготовления отливов и откосов.
Изготовление защитных элементов и корпусов, в том числе таких как рукава металлические (для защиты кабелей от механических повреждений), изделий для заземления.
Производство перфорированной ленты ориентировано на изготовление таких видов продукции как лента монтажная, лента крепежная и изготовления крепежных изделий, в том числе для крепления оцинкованных профилей.
